A rebellion is like a disease; if you let it linger for too long, it will spread, the idea behind it taking root in the public. It will have to be dealt with as soon as possible and as violently as possible. Seek out every single member of the rebellion and kill them. Both Caydiid and Abdullahi Yusuf opposed Siad Barre's(AUN) rule from the very beginning. Why did he imprison them for years just to let them free and be the downfall of his government when he could have had them killed in prison? As for the Manifesto signees, it was far too late. Rebellion has to be stopped before the idea behind it reaches the general population. He should have compromised and given the citizenry the illusion of control. The manifesto group was also at odds with the armed rebels and could have been used to crush them as they had a lot of public support.Executing prisoners would have garnered him more public anger and hate. He got away with executing Salaad Gabeyre because it was early days and Salaad had many enemies.
He once imprisoned the Manifesto signees in early 1990 and sentenced them to Death, the whole of Xamar almost came to a halt that shook the regime so much they had to reduce it to imprisonment. Don't under estimate the public support.
Honestly, Caydiid had it too easy till the UN came. Afwayne use to give stars to reer baadiyo geeljirayaal who have never picked up a gun and told them to protect his govt ma waxaasaa layska dhici karin
If he was a smart leader, he would have built a loyal Army across clan lines. Instead he got paranoid when the Mj's attempted a coup and he saw many regimes in Africa overthrown by Vice Generals and Army Heads. From that moment, he surrounded himself with clansmen thugs like Morgan, Gaani, Gabyow, Dafle etc. He was even willing to tribalise the economy and gave Xoosh Kibray the only license to export and import without being taxed. How do you alienate the majority stakeholders in the country and expect to rule forever with a bunch of nobodies?
